PS: To get enough wattage for multiple drives, use a USB hub with separate power supply.
I have the same. In 11.06 everything worked fine. In 11.09 and 12.0 as soon as i use an USB 3.0 5tb with the raspberry pi 5 the raspberry freezes and when I remove the usb it works again. (i have 5 raspberry PI 5 they all do the same)
I am back to 11.06 and everything works again or I use Windows 11 PRO that also works fine with the disk on the same PI.
(i use the usb disk to watch films and series and TV (IPTV))

Can you install LE 12 on a spare microSD, and replicate the issue? If it's a software issue, then we want to find the bug.
The best advice here is to ensure your drives are formatted with the Ext4 file system. There’s plenty of reports here on LE12 and the problems with NTFS.
I converted the usb 3 5tb disk from NTFS to exfat and then it worked again.
bootloader config / EEPROM:
PSU_MAX_CURRENT=5000
